Sorry for the silly question, but what is the part between the beak and the eye that's swelling as she breathes? I've been following this camera for three years now, but I don't remember seeing that before. Even Google couldn't help me.

Hello, Lisbeth,
I see it too now... I do not know what it is. A vein? Airflow?
Someone, please?

15:06 The thunderstorm isn't over yet.
15:38:30 The hatchling is chirping again. It quacks. It is still not completely out of the egg.
15:51:15 A little help from Kati? She 'shakes' the egg a little.

comparable to sinus passages in humans??. The trachea in birds is much larger, breathing has a different principle.
